Myfinvention relates to Wheel pullers, more particularly to av device for pulling the rear,

- Wheels of an automobile from their axles, and has for its object theprovision of a device of the character designated which shall besimple of construction and operation and which shall be more durable in use than any heretofore known ft'me.v f

` In ymy prior United States Patent, No.

10 1,590,973, issued June 29th, i 1926, there is shown, described andclaimed, an automobile wheel puller embodying a compressible ring adapted to -screw onto the wheel hub and havingan externally tapered portion, and a sleeve having an internal taper litting over the ring. -Apbushing is adapted to screw into one end of the sleeve and a wedge and plunger is associated Withthe device whereby a force is applied to the end of the wheel axle which 0 exerts a compressive force on the-ringtovcause it to tightly grip "the wheel hub and prevent stripping of the threads onftlienhub when pulling the'Wheel. f

My present invention is particularly cli- V rected toward improving the device of my prior patent. While my prior invention has proved eminently satisfactory in use for pulling automobilewheels, I-"have found that the outer sleeve member, when continuously subjected to the severe strains occasioned by a driven Wedge, soon has its threads so damaged as to require yits replacement. I have furthermore found that the plunger employed with my prior device, especially Where the wheel being` pulled is tightly ,engaged .with its axle, sometimes spreads the ends of the Vwheel axle and thereby damages the threads thereon."

In accordance'with my presentinvention,

my prior patent which is` provided at one end with an internally tapered portion to cooperate With a compressible ring adapted to screw onto a wheel hub. The other end of the sleeve member is internally threaded to cooperate with an expansible ring which is adapted to screw into the sleeve and which is internally tapered. Fitting within the expansible ring is an externally tapered guide which is positioned, 4when force is applied I provide a sleeve member aside-scribed inl thereto, threads of the latter more tightly engage the threaded portion of thesleeve: Cooperating to expand the ring, whereby the with the vplunger guide is a wedge member adapted to bear against the ends ofthe plunger, which latter coopera-tes with the end of the wheel 'axle'.` rIhe plunger is made hollow and is preferably internally threaded toscrew over the end ofthe wheel' axle.' 1 f- Apparatus embodying features vof my ini vention is illustrated in the accompanying drawings, forming'a part of this application, whereinv I Fig. 1 is a longitudinal section of'my im-` proved wheel puller andfshewing it iny engagement with the huband axle of'an 'auto-l .mobile wheel;' n `4 Fig. 2l is an end view of vthe same; andi Figs. 3,"lfand 5 are sectional views taken along the lines III"-III,IV*'IV and V-`-V,
